Application filed 'May 17, 1909. Serial No. 496,340.

To all whom t may concern:

15e it known that I, WILLIAM Horrnn, a citizen of the United States,residing at Jefferson, in the county of Greene and State of Iowa, haveinvented certain new and useful Improvements in Windmill-Towers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled inthe art to which itappertains to make and use the same.

This invention relates to a windmill tower and pump operating mechanismand has for its object to provide an improved form of mechanism foroperating the pump.

A particular object of this invention is to arrange suitable mechanismonthe tower whereby the windwheel and cooperative parts may be lowered for-oiling or repairing without climbing the tower.

A further object of the invention is to provide means wherebythewindmill may be moved into and out of position for operating the pumpoperating means in order that the pump may be thrown into or out ofoperation as desired.

A further object is to provide improved means for supporting thewindmill tower and for bracing the upper end thereof.

With these and other objects in View, the

invention consists of certain novel features of construction,combination and arrangement of parts, as will be more fully describedand particularly pointed out in the appended claims. l

In the accompanying drawings, Figure 1 is an elevation of a windmilltower with the windmill frame and pump driving mechanism mountedthereon; F ig. 2 isa fragmen-A tary view of the upper end of the towerand the wind wheel frame; Fig. 3 is a similar view of the lower portionof the tower and a portion of the pump driving mechanism; Fig. 4 is ahorizontal section taken on line 4 4 of Fig. 3; Fig. 5 is a verticalsection taken on line 5-5 ofFig. 3; and Fig. 6 is a horizontal sectiontaken through the-tower at a point immediately above the wind wheelframe.

Referring to the drawings fora more particular description of theinvention, 1 indicates the supporting frame which may be of 'anysuitable construction and 2 the tower which is revolubly mounted thereonand is preferably made of gas pipe.' The upper end of the tower isbraced by a collar 3, having upper and lower flanges 4 and 5,respectively, with which are engaged the upper and lower hooked ends 6and 7 of the bent brace rods 8, the centers of which are connected withthe ground by the guy cables 9. The collar 3 rests on the ring 5) whichis bolted to the tower 2. The wind wheel 10 has its shaft 11 mounted inthe frame 12 which, as shown, is of approximately rectangular form andis provided with a cylindrical body 13, mounted to slide upon the guidebars 14, screwed or otherwise attached to the tower 2. The inner end ofthe wind wheel sha ft is provided with the crank wheel 17, to which iseccentrically connected the upper end of the pitman 18. The lower end ofthe pitman is provided with a loop, 19, which, when the wind wheel frameis in operative position, receives the lower end 2O of the verticallymovable operating rod 21, having the upper enlarged portion or body 22,which is mounted to slide vertically through the loops 23 of the upper.and lower guide bars 24.

The operating cable, 25, is connected to the lower end, 20, of theoperating rod, 21, at its upper end, and has its lower end connected tothe center of an operating yoke, 2G. In practice, the ends of the yoke,26, are pivoted to the legs, 27, of the frame, 28, which 'encircles thetower and is securely bolted thereto. The side pieces of the operatingyoke are connected by the links, 29, with the collar, 30, which ismounted to slide vertically upon the tower and is held against rotarymovement thereon by the guide bar, 31, which is received by a recess inthe inner surface of the collar. This collar is provided with the upperand lower flanges, 32 and 33, respectively, between which is arrangedthe spliced ring, 34, which is connected by the fork, 35, with thehorizontal operating bar, 36, pivoted at its outer end as at 37, to theupright support, 38.

A vertical operating bar or link, 39, is disposed between the inner endof the bar, 36, and a second lower horizontal operating bar, 40, whichis also pivoted at its outer end as at 41, to the support, 38, and isconnected near its inner end with the piston rod,

42, of the pump, 43.- "Ihe side pieces of the wind wheel frame, 12, areconnected by means of the rods 44, with the upper end, 45, of theoperating cable', 46, which passes over a pulley, 47, suitably mountedupon the tower above the upper collar, 16. rIhis operating cable, afterpassing over the pulley, 47, passes downwardly and winds upon thewindlass, 48, which is mounted in the frame, 28.

To facilitate the winding` of the operating cable upon the windlass, thelatter is provided with the gear, 49, which intermeshes with the windingpinion, 50, arranged near one end of the shaft, 51, which extendsthrough the side pieces of the frame, 28. This shaft is provided with anoperating handle, 52, for turning the pinion, while the gear shaft isprovided with the pawl and ratchet, and 54, respectively, to preventretrograde movement of the windlass.

The extreme upper end of the tower is provided with the tailboard, 55,to cause the tower to turnwith the wind.

56 indicates an arrow which is arranged above the upper end of the towerfor indicating the direction in which the wind is blowing.

In practice, when it is desired to throw the pump, 43, into operation,the handle, 52, is turned to wind the operating cable, 46, upon thewindlass,` when the wind wheel frame is caused to slide vertically uponthe tower until brought into operative position or until the loop, 19,of the pitman, 18, engages the shoulder, 57, near the lower end of theoperating rod, 21, and consequently at each revolution of the wind wheelshaft, the operating rod is raised, which, through the medium of thecable, 25, operating yoke, 26, links, 29 and the various otherheretofore described connections, operates the pump.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction, may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim is 1. In a device ofthe class described, a base, a tower rotatably mounted thereon, a windwheel frame slidably mounted on the tower, means for raising the frame,a pivoted yoke mounted near the lower end of the tower, a verticaloperating rod mounted near the upper end of the tower, a connectionbetween said rod and the free end of said yoke, a crank wheel on thewind wheel shaft, a pitinan connected with the crank wheel and having aloop to receive the open ating rod, a shoulder on the operating rod toform a stop for the loop of the pitman, and connections between the yokeand the pump for operating the latter, when the wind wheel and its frameare in extreme raised or operative position.

2. In a device of the class described, a base, a tower rotatably mountedthereon, a wind wheel frame slidably mounted on the tower, a wind wheelmounted in said frame, manually operated means for raising the windwheel frame, a pivoted yoke near the lower end of the tower, a collarslidably mounted on the tower beneath the yoke, links between the yokeand collar, a vertical operating rod mounted near the upper end of thetower, a iexible connection between the operating rod and the pivotedend of the yoke, a crank wheel on the wind wheel shaft, a pitinanconnected with the crank wheel and having a loop to receive the lowerend of the operating rod when the wind wheel frame is in raised oroperative position, a shoulder forming a stop on the lower end of theoperating rod, and connections between the collar and the pump foroperating the latter when the wind wheel frame is in operative position.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

VILLIAM HOPPER.
